Classes | |
| struct | CategoryItem |
| CategoryItemModel::CategoryItemModel | ( | QObject * | parent = 0 |
) |
Constructs a category item model with the given parent.
| CategoryItemModel::CategoryItemModel | ( | DigestDbController * | controller, | |
| QObject * | parent = 0 | |||
| ) |
Constructs a category item model with the given parent and attaches itself to the controller.
| CategoryItemModel::~CategoryItemModel | ( | ) | [virtual] |
Destroys the category item model.
| CategoryItemModel::Q_DECLARE_FLAGS | ( | ModelFlags | , | |
| ModelFlag | ||||
| ) |
| CategoryItemModel::ModelFlags CategoryItemModel::modelFlags | ( | ) | [inline] |
Retruns the category item model's flags.
Not to be confused with the version for individual items, flags(const QModelIndex&).
Defaults to: ItemsAreSelectable | ItemsAreEditable
| void CategoryItemModel::setModelFlags | ( | ModelFlags | flags | ) |
Sets the category item model's flags.
Defaults to: ItemsAreSelectable | ItemsAreEditable
| CategoryItemModel::IndexType CategoryItemModel::indexType | ( | const QModelIndex & | index | ) | const |
| int CategoryItemModel::indexDatabaseId | ( | const QModelIndex & | index | ) | const |
This is specific to the SQL table that the index lives in.
Use indexType() to determine which table the index lives in.
| QModelIndex CategoryItemModel::libraryIndex | ( | ) | const [inline] |
| Qt::ItemFlags CategoryItemModel::flags | ( | const QModelIndex & | index | ) | const [virtual] |
| int CategoryItemModel::rowCount | ( | const QModelIndex & | parent = QModelIndex() |
) | const [virtual] |
| int CategoryItemModel::columnCount | ( | const QModelIndex & | parent = QModelIndex() |
) | const [virtual] |
| QVariant CategoryItemModel::headerData | ( | int | section, | |
| Qt::Orientation | orientation, | |||
| int | role = Qt::DisplayRole | |||
| ) | const [virtual] |
| QModelIndex CategoryItemModel::parent | ( | const QModelIndex & | index | ) | const [virtual] |
| QModelIndex CategoryItemModel::index | ( | int | row, | |
| int | column, | |||
| const QModelIndex & | parent = QModelIndex() | |||
| ) | const [virtual] |
| QVariant CategoryItemModel::data | ( | const QModelIndex & | index, | |
| int | role = Qt::DisplayRole | |||
| ) | const [virtual] |
| bool CategoryItemModel::setData | ( | const QModelIndex & | index, | |
| const QVariant & | value, | |||
| int | role = Qt::EditRole | |||
| ) | [virtual] |
| Qt::DropActions CategoryItemModel::supportedDropActions | ( | ) | const |
| QStringList CategoryItemModel::mimeTypes | ( | ) | const [virtual] |
| bool CategoryItemModel::dropMimeData | ( | const QMimeData * | data, | |
| Qt::DropAction | action, | |||
| int | row, | |||
| int | column, | |||
| const QModelIndex & | index | |||
| ) | [virtual] |
Warning: index has been renamed from parent, because the latter lead to much confusion, as it really is the index of the item that the MIME data was dropped onto.
| QModelIndexList CategoryItemModel::checkedIndexes | ( | ) | const |
| QString CategoryItemModel::gestureQueryForIndexes | ( | const QModelIndexList & | indexes | ) | const |
| QString CategoryItemModel::gestureQueryForCheckedIndexes | ( | ) | const |
Convenience method.
Equivalent to gestureQueryForIndexes( checkedIndexes() );
| bool CategoryItemModel::isReady | ( | ) | const [inline] |
| void CategoryItemModel::resetEvent | ( | VEvent * | ) | [protected, virtual] |
Resets the model.
Calls resetModel(), followed by reset() (which resets the views).
Reimplemented from AbstractDigestDbView.
| void CategoryItemModel::classesEvent | ( | VClassesEvent * | event | ) | [protected, virtual] |
Note: "Classes" live in the Library, which I believe is logical.
Reimplemented from AbstractDigestDbView.
| void CategoryItemModel::collectionsEvent | ( | VCollectionsEvent * | ) | [protected, virtual] |
Reimplemented from AbstractDigestDbView.
| void CategoryItemModel::resetModel | ( | ) | [protected] |
| QModelIndex CategoryItemModel::index | ( | CategoryItem * | item | ) | const [protected] |
We employ caching in this method, as it called very often by the views and contains a very expensive line of code that includes createIndex() and the very costly indexOf() (which performs a linear search).
Asserts that the item is non-null.
| QModelIndexList CategoryItemModel::checkedIndexes | ( | CategoryItem * | parent | ) | const [protected] |
Light-weight, recursive method - used by checkedIndexes().
Asserts m_ready and that parent is non-null.
